[SOLVED] Proxmox Node>Summary show graphics always blank

[KsK]

Hi, I have read several posts with the same problem (example) and I have reached a different point and I have not found how to continue to solve it.

systemctl status pvestatd.service is OK

and pvesh get /nodes/pve/rrddata -timeframe hour --output-format json-pretty drops
got wrong time resolution (604800 != 60)

how can I solve this?
thanks in advance ^_^

What is the output of systemctl status rrdcached.service?

Okay, this is also running.
Did you try to change the time scope on the upper right corner of the graphs?

 

[KsK]

of course .. and nothing changes

 

[ph0x]

Hm, no clue then.

 

[KsK]

seems the problem is in time resolution, something relative to years ..
got wrong time resolution (604800 != 60)
604800 is 60 * 10080 and don't remeber where I read that number near years ..

 

[ph0x]

604800 seconds is a week, though. ;-)

 

[KsK]

maybe .. but how can I solve that problem?
pvesh get /nodes/pve/rrddata -timeframe hour --output-format json-pretty should drop info like:

but show got wrong time resolution (604800 != 60) :_(

ok .. today I've seen that date begins in 1970, searching that in forums found this and there explain that
remove proxmox rdd file in /var/lib/rrdcached/db/pve2-node make it works.

SOLVED.
